Serial No. 720,644. l

To al@ whom it may concern Beit known that l, HUGO BRUCKMANN, electrician, a subject of the German llmperor, residing at Benrath, Germany, have invented certain new and useful Improve4 ments in Calculating Mechanism, of which the following is a specification.

This invention relates to an apparatus for use in calculating' charges for the consumption of gas, electricity,'water and so forth.

lt is the principal object of the invention to provide such an apparatus with sets of numeral Iwheels for in'tiioating the meter readings at the beginning and end of the periodto be charged for, and means for indicating the difference of these rea-dingsy automatically 'on another set of wheels, means for multiplying vthe said. dill'erenoe by a number representing the charge per unit, and means for showing the result on numeral wheels. '1

A further object is Vto vprovide wheels for y recording a fixed charge, as for meter rent,

and for enabling that charge to be added to the product obtained by multiplication.

,Other objects are, toprovide means for preventing the tens carried from one wheel to another'in the setting of the second meter reading, from being transmitted to the Wheels which show ,A the difference between the two readings; and to provide convenient means. for the automatic restoration to their zero positions after/each accounting operation, of the wheels and parts whose settings vary each time, while leaving the figures such as the rate per. unit and the charge for meter rent, permanently set in the machine until these require to be altered by hand.

"Other objects will appear from the following description.

The invention is illustrated by way of eX- ample in the drawings wherein :w

AFigure 1t is a front elevation of the left hand part of the apparatus with the coter broken away. Fig: 1b is asimilar View of the right hand part of the apparatus. YFigs. Q and 2" are top plan views corresponding with Figs. l"l and 1l. the cover of the casing being pai-tlv broken away. Fig. is a section on the line A B of Fig. 1% Fie'. i a

5 is ,a sectinn/dz/i ,the linflMF of F ig. is a section on the line G--H of- Fig. l, Fig. 7 is a section on the line I-K of rigs. 1fL and 1b. Fig. 8 shows two coperating stepped multiplying diskspgf known type as used in this machine. Figs. .'9 to 12 are detail views. Fig. 13 is4 a diagram illustrating the process of multiplication.

ln the drawings, all the sets of numeral wheels can be seen in'lligs. 1a and 1b, 2a and 2b. The numeral wheels can all be turned as hereinafter described in order to cause them .to show through apertures in the casing, numbers corresponding to the positions ing only thelirst reading. The wheels 91,

2Q, 23 are operatively connec-ted respectively to the wheels 2, 3, and t only, during the sees( ond setting of the lat-ter, so that these wheels show only 'the difference between the two settings, representing the number of units consumed in the period to be charged for. ylhe wheels 181 and 182 are set to show the charge per unit, and these wheels cooperate with the wheels il to 23 in moving the stepped multiplying disks 1.1.4 to so as to bring about the multiplying operation. The wheels 164 to 16S are intended to show the inet-er rent'or other iixed charges.' The wheels 142 to 146 are set by hand to 'show first such iixed charges. being connected to the wheels 164 to 168 daring their setting. and afterward disconnected therefrom and connected to wheels 15S to 162. Theinwhen the multiplying operation is effected by turning a handle 104, 'the wheels 142 to 146 and .158 to 162 are turned forward by the amount of the product of the multiplication, and the latter wheels show this product, while the former show this product plus the fixed charges.

After this brief description of the principal parts of the apparatus, will now proceed to describe in detail the various parts and their associated mechanisms,

The lever i if 'fo be-moved up and down several tinies 4part of its arent movement wherein its pende engages with the toothed Wheel l0, in order tofstep forward the numerelfvheel to bring i the required ligure under the slot in the easing as in .Fig.'2a. After the setting, the iever' "7'1s'restoredxto its raised position 'wherein ,itsfpawl 5 is not engaging its toothed Wheel x10. 'The saine aetion takes place in case lor the lever' 6. which serves for setting the numeral Wheel 3'.

Thel'ever 5 needs to have no segment for throwing n transmission pinion out of aetion, as 'its numeral Wheel 2 is` the highest (hundreds) Wheel 'from which no ten is earriedv infr-'this inaehine. This lever Would therefore need to have no pin and guide device such as is described above for the levers' and l7 for the purpose of preventing` the carryingo'f tens before the Connecting` gears between lthe wheels 2 4 and 21u23 have been thro-'Wn out ofaetion. rThere is another purpose served by the pins and.

guides however7 namely to hold the pawls' of the setting levers out ot notion in order to permit. thefnumeral Wheels to be re- -tstored to their zero positions as hereinafter described, Without being stopped by said levers. Hence, the lever 5 also has a pin 40u on its pawl whichjengages over a guide 42 to hold said pa-Wl out of action when the lever 5 is raised after each operation of turning the wheel 2 by said lever.

A lever 172 (Figs. l, 2a, et and 9) is rev- .olulolyjsupported on the shaft l rnd has a segment piece 173 attached to it. This segment. piece is formed with inclined edge ot' tie segments the le e 7 to the sh 'tis of hes asmall pro- '.6 is pivoted. The .end which embraces ral Wheels lli-l5),

-rne tact-hed ring of the numeral wheel drives a pinion 72 revolubly mounted on the sleeve which connects the pinions 65 and pinion 72 being made in one` with or smaller pinion 7 3. This pinion 73 transmits the motion to a pinion 7d revoluioly mounted on the shaft 59, and pinion 74; in turn actuates altoothed wheel 75 fined on a horllow shaft or sleeve 76. rllhe sleeve 7 6 carries at its other end two ratchet wheels 77 and 78 which are engaged by pawls on the stepped disks e9 and 50. The hollow shafts 52, 69 and 76 rotate around a' substantial anis 79, the shaft ,62 working. directly over this axle, shaft 76 in turn working around the shaft 62, and shaft 69 around shaft 76. lBy means of the ratchet wheels 03 and 64, 70 and 71, 7 7 and 78, and hy lthe pawls engaging therewith op the tepped disks 53 and 5d, 45 and 46, di and 0, itis possible to turn the. stepped disks from the numeral wheels .2l-23 by i....eans of the intermediate' 'gearing and the shafts 62, 69 and 76, but it is also possible to. adjust the stepped disks 411 forwardly without the numeral wheelsv .2123 being carried around, or without the motion being' conveyed from the said numeral wheels.

The stepped or notched disks 44-55 are of s. type known already in calculating Ina-if' shines. They operate in pairs, the odd-numhered disks (the right hand in each pair) having the units notches in them, while th even-numbered disks (the left-hand in each air), have 'only the tens notches. The depths of the notches, correspond to the numbers in question; for instance the notch for the number 1 is one unit in depth, while the notch for the number 9 isnine units in y depth. Fach disk is diyideddnto 10 sectors, as indicated in Fig. 8l In that figure the upper disk is a units disk (45, 47, 419, 51, 53, and `55), while-the lower disk is a tens disk (se, i6, 49, 50, 52 and 5&1). The sectors are numbered O, l, Il, Ill, lV, V, VI, VH, VH1, 1X, while the numbers at the edges of 'the disks correspond with the depths of the notches. Sector l of each disk d5, 47, 49, 51., 53 and 55 contains the notches for the products of the numbers from 0 to 9 multiplied by 1;-sector ll contains the notches for the unit igures of the products of the numbers 0 to 9 multiplied by 2; sector III contains the notches'of the unit figures of the products of the numbersO to 9 1nultiplied by 3, and so forth. rlhe corresponding sectors in the tens disks 44, 46, 48, 50, 52 and 5d contain only the tens notches of the ai products in corresponding positions.

example, ,the number 27 being the prodindicated in sector. III by a notch seven units deep in the units disk, and a notch two units deep in the tens disk.

ln the notches of the stepped disks dll', pins 79-90 are adapted to'engage (Figs. 2b and 7). These pins slidethrough guides '80, and, levers 90-101 mounted to turn freely on an aXl'e 102 have their free ends connected with the pins 7 9-90 by means of lateral projections 91 on the pins engaging in slots in the levers. On the other side double armed levers 107-118 turning on a shaft 131, and having their rear arms pulled up by springs 106, engage also with the projections 81, and tend to force the pins 7 9-90 downward. Beside 'the axle 102 a shaft 103 is arranged',wlich shaft can be turned in one .direction by means of the handle 104:, through a one-way clutch 221 connecting' the boss of the handle to said shaft. On the shaft 103 are fixed a number of cams 105 (Figs. 2, 7 and 11), one for each of the pins'79l-90. The portions 10FEL of the cams 105 are circular in circum-v ference; so they hold the levers 90-101 in their raisedposition as is seen lin Fig. 7 lf however, the cam disks 105 are turned in the direction of the arrow Fig. 7, their faces 105b come successively opposite the faces of the levers 90--101 and allow these to fall. When the faces 10,5c come against the levers 90-101 they move the said levers upward again until the position of Fig. 7 is again reached. As the levers 90-101 are linked with the pins 79-90 the said pins are moved first dwnward and then upward with the levers. The pins 79-90 however only move downward as far as is allowed by the respective notches of the stepped disks llid-55 which lie directly in' the path of said pins. The levers 107-119 are ,attached to toothed wheels 119-130 (Figs. 1", 2b, and 7) which are revolubly mounted on the shaft 131. When the pins 79-90 engage in the notches of the disks 14k-55, the elbow levers 107-118 move'at the same time 'arid -to a corresponding cxtent, and transmit the movement as a turning movement -to the toothed wheels 119-130, which latter transmit the movement to tive toothed wheels 132-'136 which are revolubly mounted on the shaft 1. The transmission of the movement is effected by pipions on shafts 137, 138.-and 139 because all the toothed wheels 119-130 cannot possibly gear simultaneously with the toothed wheels 132-186. The toothed wheel 119 gears directly with the toothed wheel 132; the wheels 120, 121 and 123 actuate the wheel 133 by means of pinions fixed on the revoluble shaft 137'; the wheels 122, 124, 125 and 127 actuate the toothed wheel 134 by means of pinions on the shaft 138; the wheels 126, 128 and 129, actuate the toothed wheel 135 by means of the pinions fixed on' the shaft 139'; and the interposition' of the pawls 137-141, it isA possible for the numeral wheels 142-146 to be turned. .without the toothed wheelsv 132-136 being moved; moreover, only the forward movements of the uwheels 119-130 will affect the positions of the numeral wheels 142-446.

\ The numeralwheels 142-146, like the'numeral wheels 2-4, can he adjusted by means of hand levers 1ML-155n (Figs. 1b, 2, and 7), said hand levers having pawls 251 .which engage with toothed wheels 252 connected to the numeral wheels 142-146. Rings .et teeth 147-151 on the numeral wheels 142-146 engage with pini'ons 157 which are revolulole on a shaft 156, and which in .turn 'gear with the teeth of numeral wheels 158-162. The shaft 156 of the intermediate pinion's 157 can he moved laterally togetherv with said inions by means of the lever 156a mounted t rock longitudinally about a stub 156, so that the intermediate pinio'ns 157 can be moved out of engagement with the numeral wheels 158-162 and with the toothed rings 147-151 of the numeral wheels l142-146L The numeral wheels 164-168 are revolubly mounted Von a shaft 163, and have rings of teeth which also engage with the toothed rings 147-151 voft the numeral wheels 142-146 (Figs. 1b and 7). .The shaft 163 can be moved 'so as to 'bringthe numeral.

wheels 164-168 out of Aengagement with the teeth 147-151 off "the numeral wheels 142-146, This is eiieoted by a. double armed lever 169 whichy rocks about a' stub lflanutside the casing and engages with a boss formed on the vend of theshaft 163.

' `The numeral wheels 142-146 have, like l `the numeral wheels 2-4, devicesfor carryving forward the' tens, arranged. on shafts 1702, 170B, (Fig. 7) and operating in a similar manner.

.The numeral wheels 181 and 182 which serve for showing the charge per unit, (by which amount the difference between the two meter readings is to be multiplied in order th get the charge for the total units used in the period in question) are adjusted to show the required charge by means of levers 183 and 184 having pawls which engage with the toothed lrings 261 and 262 of said numeral wheels. These numeral wheels transmit their movements to the stepped disks 44-55 in the following way:-The toothed rings l261 and 262 drive respectively toothed wheels 263 and 264 whichl run loosely on a shaft 271, and are united to toothed wheels 265 and 266 hy sleeves 267 and 268. The toothed wheel 265 Fig. 1n? drives a pinion 269 ixed on a shaft 183g, while the toothed Wheel 266drives through a gear train 27 0, a pinion 272 xed on. shaft 184i Gn the shaft 183*l (Figs. 1b and 6) are alsomounted toothed wheels 18S-187 which engage with toothed rings 18S-190 iiXed between and at tached respectively to the pairs of stepped disks 44 and 45, 48 and 49, 52 and 53. On the shaft- 184a are mounted toothed wheels 191-193 which similarly engage with toothed rings 194-196 between the steeped disks 46 and 47, 50`and 51, 54 and 55. The ratio of the gears is so chosen that the toothed rings 18S-190 and 194-196 make a cour plete revolution for a quarter revolution oi the numeral wheels 181 and 182. stepped disks 44-55 are caused to turn with the toothed rings 18S-190` and 194-196 which are iiXed to them, so that the turning oi the numeral wheels 181 and 182 through any angle of movement results in the movement of the six stepped disks connected with each wheel 181 and 182 through four times that angle of movement. Each quarter of the numeral wheels 181 and 182 is marked circumferentially with the numbers A(l to 9, so that when the said numeral wheels are moved hy one number space, the stepped. disks 44-55 are turned hy a tenth part of a revolution z'. e., one of the sector spaces I. Il, etc.

As already explained, the movement of th stepped disk does not aifeot the numera vWheels 2 1-23 because the catches of the stepped disks 4-4-55 simply slip over the 62 and 64.

The way in which .the apparatus operates will be made clear by taking an example as follows:-A. meter` for electric current showed at the'end orn a month for example that 358 kilowatt-hours had been consumed. After another month the meter showed 872,

this month. The consumer has to payy say 14 cents per kilowatt-hour. rl`his would give a sum of 71 dollars 96 cents for the 514 kilowatt-hours, to which is to he added dollars 2.50 for the meter rent in that month. It is assumed that 'all lthe numeral wheels 2-4, N ia, ei-Qa, 15s-ionisants, 181, 182, and 142-146, and also the stepped. disks 44-55 stand at O, so that the numeral 0 shows at all the openings in the casing over the numeral wheels, and that in front of the pins 79-90 is in veach case the beginning of the sector O. of the correspondin stepped disks 44-55.

The

the wheels 2-4 and 17-19 will be explained first. A lever 199 (Figs. 1l and 4) 'is pivoted by a pin on the segment 173, and itis slotted so as to work over `a pinA 201. |The lever 199 is shown in full and dotted lines in its vtwo extreme positions in Fig. 4. On the pin 201 is a spring 227 pressing the lever 199 toward the right, Fig. 12. v'A lever pivoted at 204 has one arm 202 projecting into the path or' lever 199, while its other arm 203 is pulled by a spring 225 so as to hold the arm 202 normally pressed againstl a stop 226. In this position, when the segment 173 is moving downward, the inclined end ot lever 199 seen in Fig. 12, will slide past the lever 202 until a notch at 200 in the lever 199 snaps into engagement with lever 202 under the action of spring 227, as in Fig. 12. Then when the segment 173 rises again it will draw up lever 199, and'this will pull upl lever 202 vuntil the end of said lever slips out of tlhe notch 200, when the spring 225 will resttre lever 202 to the position shown.` The lever arm 203 is in turn linked to a slotted lever'205 which works over a pin 201l5and engages by its notch at 206 with a lev `r 207i The turning .of lever 203 pulls lever l2,05 toward the right, Fig. 4, causing'lever 207 to turn in a countenclockwise direction. Lever 207 is pivoted at 208 on the slide 20a whifch carries the shaft 20 of' the numeral wheejs 17-'19, and said lever has a projection carrying the axis 209 of the. l pavvls 180.

On the shaft 204 a cam or projection 210 is fixed (Fig. 3). Slt now the lever 202 is moved upward as c esclibed by means of the lever 199, theshailt 204 is turned together with vthe projection 210, which latterfraises the end ot the catches' 177-179 which rest upon it. The catches are thus turned about their shaft, and the parts of the catches engaging inv the toothed wheels 84-10 are moved out of engagement with the teeth so leaving the numeral wheels 2, 3 and 4 free- (Figs. 1, 2L and;` 3). At the beginning of the movement ofi the numeral wheels 2 4, cords 211a or the* like, which v`are connected with springs'211, `have been coiled on bosses on the intermediate wheels 1 4-16 (Fig. 3), and these cords tend to turn back the intermediate wheels, and the numeral Wheels 2-4 with which they engage, to their zero position, but are prevented from doing this 4by the catches 177-179; the cords will however turn back the said numeral wheels 2-4 to their Zero position when the catches 1TTW179 have been disengaged from the toothed wheels 8-10.

The lever 205 is moved by the arm 203 of the elbow lever 202 at the same time as the projection 21.0 is turned. and the lever 205 mores the lever 207. Consequently the shaft 20) carrying the. pawls 130 is moved downward at the same time, so that the pawls numeral wheels Loeaes whose rear arms'rest against shaft 203 are caused to turn backwardly'and to become disengaged from the ratchet wheels o' the 17-19. These numeral wheels, like the intermediate pinions 14 16 have cords 211c with springs 211b which tend to move them back to their zero position but are normally prevented from doing so by the pawls 180. In the first part of the upward movement of the segment 173 the link 176 is allowing the shaft 20 and the numeral wheels 17419 to move 'forward again under the action of the spring 20", but these wheels do not engage with the wheels 14-16 until after the catches 17 7- '17 9 and 180 havebeen moved out of engagement with their respective toothed wheels or ratchets by the action oli' the'levers 200,

205, 207.- Hence, during the first part of the upwardmovement of" the segment 173 the springsV 211 and 211b are allowed to turn back the wheels 14-16 and 17-19 independently to their zero positions by means of the cords 211n and 211C. The turning back of the wheels 14-16 also restores the i numeral wheels 2--4 to their Zero position. After this restoration is complete, the lever 202 becomes released from the'levcr 199 and returns to the position shown in 4, so that the catches 177-179 and 180 again engage with their respective wheels. The `further movement also of the segment 17 3. will have brought the numeral wheels 17-19 'into gear again with' the wheels 14-16 so that the se'ts of numeral wheels 2 4 and 17-19 are ready. for a fresh accounting operation.

The numeral wheels 142-146 and 158- 162 are'returned to their starting positions as follows z-Each of the pinions 157 (which turn freely on shaft 156), has aprojection 212 Fig. '7, adapted to be engaged by a spring pawl 214 attached to a disk on the shaft. The shaft 156 also carries atits right hand end, Fig. 2b (dotted lines) a toothed wheel 228 which meshes with a. pin-- ion 215, this latter in turn meshing with the toothedv wheel 223 on shaft1 vVlhen "the shaft 1 is turned forwardly through 90 hy the gears 222, 220, 223 during the forward turning of the handle 104, the shaft 1 carries around none of the wheels which turn freely'oni'it, but it turns the pinion 215 which is one quarter as large as the wheel 223, in the vdirection of the arrow Fig. 7, whereby the shaft 156 is turned backwardly through one revolution, while its pawls 214 snapl under each of the project-ions 212 of pinions 157 whateverl the positions ot these may be. Then, when handle 104 is turned hack, and the wheel 223 is also turned backwardly, the pinion 215 turns the shaft 156 forward again through one revolution. In
